Part 2: Cognex LCD Vehicle Display Tester

by

Welcome back to the blog! Today, I will be talking about how to operate a Cognex smart camera via a LabVIEW program. The way I will be communicating with the camera is via TCP/IP. There are other potential ways to communicate with the camera from LabVIEW, but this was determined to be the best way, giving us the most control over the camera. I will walk through some basic terminology that is necessary to discuss building a Cognex vision test. Then, I will create and set up a vision test and finally, I will briefly describe how to program LabVIEW to send/receive information to the camera and to trigger an image acquisition.

As LCD vehicle displays have become more prevalent and versatile in both on- and off-highway, the time it takes to ensure proper display functionality after a software release has increased dramatically. It is not uncommon for displays to have 15, 20, or even 30 different screens, each of which having multiple sub-selections available. If you take into consideration different supported languages, the scope of the test grows dramatically. DISTek, as a company, is always attempting to define the future needs of customers in the off-highway industry, of which vehicle display testers are one of those needs.

NI Week 2016: LabVIEW Champions Track

by

Ni Week

The 22nd Annual NI Week is slated to begin in Austin, Texas, on August 1st. NI Week provides the forum to bring together the brightest minds in engineering and science. More than 3,200 innovators representing a wide spectrum of industries, from automotive and telecommunications to robotics and energy will converge together to discover the latest technology to accelerate productivity for software-defined systems in test, measurement, and control. While DISTek regularly attends in various capacities, this year we will be making a new showing. Our very own Systems Engineer and LabVIEW expert, Ed Dickens, will be presenting on Wednesday, August 3rd from 4:45-5:45PM. His presentation is the result of National Instruments trying something new. This year, for the first time ever, there will be an advanced software topic track where all the presentation topics and content will be prepared and presented by various “LabVIEW Champions”.

Brainless LabVIEW Programming: CLA Summit 2016

One of the presentations I attended at this years Certified LabVIEW Architects summit was given by Darren Nattinger of National Instruments. Darren is a Principal Engineer in LabVIEW R & D. One of the many things he’s responsible for is getting the Quick Drop feature added to LabVIEW. His presentation was titled, ”An End to Brainless LabVIEW Programming”.

In March I attended the Certified LabVIEW Architects Summit (CLA) in Austin, Texas. Every year National Instruments hosts this conference where CLAs can network, discuss best practices, and share ideas. This year the theme was Continuous Improvement: Building Better LabVIEW Applications.

Integrated Projects Engineering Overview

IPE Team

If you’re a regular reader of this blog, then you probably know a lot of about the areas that DISTek works within. Our expertise ranges across the off-highway vehicle industry (including agriculture, construction, and forestry) with engineers that specialize in a variety of disciplines. Out of convenience, we typically group these disciplines into three big areas (“embedded software”, “automation and test”, and “modeling and simulation”), but the reality is that we do all kinds of projects that cross-over between these disciplines.

The DISTek Year in Review – 2015

by

DSM

Another year has come and gone and many eventful happenings took place in the history of DISTek. We may look back at 2015 as a turning point due to the substantial changes we made in all aspects of our business. Those end-of-the-year cards you get in the mail always seem to be bragging a little too much, but that is just what I am going to do because I think the year DISTek had is worth bragging about.

DAQmx in Measurement Studio: Part 3

by

The last two months we have covered how to do data acquisition in .NET. This month we will go over how to integrate LabVIEW and .NET together in a hybrid application. I am going to demonstrate how to use a LabVIEW server application to acquire data using DAQmx and send it to a .NET client application. The client can then display the data using more visually appealing Microsoft controls and then sends the data back to the server to demonstrate two-way TCP communication.

DAQmx in Measurement Studio: Part 2

by

Last month we discussed a little bit about what National Instruments DAQmx and Measurement Studio are and how they can be used to create .NET applications which leverage National Instruments data acquisition hardware. This month we are going to jump in to a high-level practical explanation on how to get started doing data acquisition in .NET.
